PurposeTrial data shows modest reductions in leg pain, disability and surgery avoidance following epidural steroid injections (ESI) for severe sciatica. Despite their common use, there is no clear evidence about which patients are more likely to benefit from ESI. The aim of this study was to generate consensus on potential predictors of outcome following ESI for disc-related sciatica.MethodsA list of potential predictors of outcome was generated during a consensus meeting of seven experts. The items were subsequently presented in a two round on-line Delphi study to generate consensus among experts on which items are potential predictors of outcome. Consensus was defined as 70% agreement among participants.ResultsSixty-one items were generated during the consensus meeting. Of ninety experts invited to participate in the on-line Delphi study, 44 (48%) and 33 (73%) took part in rounds one and two respectively. Twenty-eight additional items suggested by participants in round one were included in round two. Overall, 14 items reached consensus reflecting domains of health, medication use, pain intensity, psychosocial factors, imaging findings and type of injection.ConclusionBased on expert consensus, items that can be routinely collected in clinical practice were identified as potential predictors of outcomes following ESI.© 2024.
